What Is a Fully Automatic Concrete Compression Testing Machine?

The Automatic Concrete Compression Tester determines the compressive strength of hardened concrete cube and cylinder specimens. The system applies load to the specimen at a controlled rate, records the failure load and calculates the test result automatically.

LİYA Test offers 2000 kN and 3000 kN configurations for different laboratory requirements. EN and ASTM versions are available with different compression platen arrangements.

The fully automatic test cycle reduces operator influence and supports consistent testing of both conventional and high-strength concrete specimens.

7-Inch TFT Touchscreen Control

The machine is controlled through a 7-inch TFT touchscreen.

The operator can enter specimen type, dimensions and test parameters directly from the display. During testing, the system continuously shows the applied load, loading rate and test progress.

Real-time load-time graphs allow the user to observe specimen behaviour throughout the loading cycle.

Once the specimen fails, the system records the maximum load and automatically completes the test.

Fully Automatic Loading Cycle

The system manages rapid piston approach, controlled loading and test termination automatically.

At the beginning of the cycle, the piston approaches the specimen rapidly. Once contact is established, the machine switches to the programmed test rate.

The loading rate is then maintained according to the selected test settings. When specimen failure is detected, hydraulic loading stops automatically.

This operating principle improves repeatability and reduces manual intervention during routine laboratory testing.

Two-Stage Hydraulic Power System

The hydraulic system combines a gear pump and a high-pressure radial piston pump.

The gear pump provides rapid piston movement during the initial approach. The radial piston pump then delivers the pressure required for controlled compression testing.

The hydraulic system operates at a maximum working pressure of approximately 410 bar.

This two-stage design combines fast specimen positioning with stable loading during the actual compression test.

Hardened Compression Platens

The upper and lower compression platens are manufactured from high-quality steel.

The platen surfaces are hardened to approximately 55–60 HRC and finished to a surface roughness of 3.2 µm or less.

A smooth and rigid loading surface helps transfer compressive force evenly to the specimen.

Different platen configurations are available for EN and ASTM testing requirements.

2000 and 3000 kN Capacity Options

The LT-C0200 and LT-C0210 models provide a maximum testing capacity of 2000 kN.

The LT-C0300 and LT-C0310 models increase the maximum capacity to 3000 kN.

Both EN and ASTM configurations are available. This allows laboratories to select the appropriate loading frame and platen arrangement for their test programme.

Modular Specimen Testing

The machine can test concrete cubes and cylinders using the appropriate loading platens.

Distance pieces can be installed when the vertical testing space must be reduced for smaller specimens.

An optional sliding block platen system also allows laboratories to switch to concrete block, brick and similar masonry tests without completely rebuilding the loading arrangement.

This modular structure extends the application range of the machine.

Digital Data Management and Reporting

The Digital Data Acquisition & Control System records test information throughout the compression cycle.

Compatible computer software allows users to store results, review previous tests and prepare reports.

This makes it easier to compare concrete mixtures, production batches or curing periods.

The integrated data system also supports more organised quality-control documentation.

Advanced Safety Systems

Several safety features support controlled operation during high-capacity compression testing.

The emergency stop button allows immediate shutdown when required.

A piston limit switch prevents excessive movement, while a maximum pressure valve protects the hydraulic circuit against overload.

Front and rear protective doors help contain fragments that may be released when the concrete specimen fails.

Testing According to International Standards

EN 12390-3 covers the determination of compressive strength of hardened concrete specimens.

EN 12390-4 defines performance requirements for compression testing machines used for concrete testing.

The product range also supports applications associated with ASTM C39/C39M, BS 1881 and GOST 10180-2012.
